BATTER GARE MACHINE.

Application filed August 25, 1916. Serial No. 116,939.

will by means of a peel, pick up a batter cake, turn it over, and drop it back upon the cooking surface or griddle and then after a redetermined interval of time,

, againpic up the cake and carry it toone side and drop it into a suitable receptacle placed for the purpose, repeating these operations in the order named as long as power is applied to it.

With this general object in view the invention consists in certain novel and peculiar features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood reference is, to be had to the accompanying drawings, in which:

Figure 1, is a side elevation of a batter cake machine embodying the invention.

Fig. 2, is a top plan view with the-top .of the frame-work omitted.

Fig. 8, is a horizontal section taken on. the line HIIII of Fig. 1.-

Fig. 4, is an enlarged front view of the machine.

Fig. 5, is an enlarged fragmentary section showing part of the mechanism for swinging and rotating the peel.

Fig. 6, is a view of the opposite side of the peel-guiding device from that shown by Fig. 1.

F 1g. 7, is a vertical section showing the connection between the peel and the carrying shaft therefor.

In the said drawings where like reference characters identify corresponding parts in all the figures, l and 2 indicate the top and bottom of the frame-work of the machine, and 3 posts or standards secured to the bottom and supporting the top, one of the front. standards 8 being set back preferably, as shown, for a purpose which hereinafter appears.

Near the rear standards, the frame is provided with a pair ofside bars a providing Specification of Letters Patent;

. suitable type.

15 against which the cam lugs nately apply pressure, to impart forward Patented May f, 1918.

a bearing for a transverse shaft 5, adapted to be driven continuously at a relatively slow speed by a motor, not shown ofany Preferably the she: at one end will carry a worm wheel5 meshing with and driven by a suitably-supported worm 5", and the motor referred to will be connected in any suitable manner, to drive the worm.

Secured rigidly on shaft 5 is a pair of disks 6 spaced apart, and each provided at corresponding points with peripheral cam lugs 7 and at other corresponding points with peripheral cam lugs 8, and rigidly secured to or formed integrally with said disks 6 is a pair of larger disks 9 and 10, disk 9 having a cam shoulder 11 for efiecting the turning of a cake upon a griddle so that the opposite side of the cake shall bake. The disk 10 has a similar shoulder 12 for causing the peel, hereinafter desame into a suitable receptacle.

A lever 13, is pivotally suspended from hearing 14, depending from the top 2, and is adapted to swing forward and backward between the spaced disks 6 forward of the shaft 5, the said lever havin a cross-pin and 8 altermovement to the peel, as hereinafter explained, it being apparent that as thedisks are provided with two sets of earns, the peel must be advanced twice in each revolution of shaft 5. The lower end of the lever 13 operates between a pair of'guides 16 upon the base or bottom 1, and is provided with a curved slot 17 engaged by a cross-pin 18 secured in the rear end of a shaft 19. Said shaft is mounted to slide and rotate in a yoke 20 having a central pivot or trunnion 21 journaled in a socket 22 in the base or bottom 1.-' The yoke is provided withan upwardly-projecting tubular arm 23 in alinement with the said trunnion, and extending through and journaled in said arm 23 is a shaft 24 which is journaled a its upper end in the top 2 of the frame-work, and constitutes the upper trunnion for the yoke.

The shaft 24- is equipped above the yoke with a cog wheel 25 meshing with a slidrear end of said rac: bar being held in the path of shoulder 11 by means of a retractile spring 28 attached at its front end to the said slide her and at its rear end to one of the guides 52?. i

A slidable her 29 is likewise mounted in the guides 9J1 engages a cog wheel 30 secured to the upper end of the yoke arm 23, and said rack bar 29 is held in the path of movement oft shoulder 12 Toy aretraotile spring 31 secured at its "front end to said raclrhar and at its rear end to one of the guides 2?.

Secured on the lower end shaft 2% within the yoke 20, is a beveled gear 82 ennieshed with a beveled gear 33 keyed or otherwise mounted upon shaft 19 to turn the same without interfering with or pertaking of its sliding movement.

From the fore oing it will be seen that under the rotation of shaft 5' in the direction indicated by the arrow, Fig. 1 shoulder 11 once, in each revolution, will en gage and slide oar 26 and thereby through the engagement of said her with cog wheel 25 transmit newer through shaft 24 and gear wheels 32 and 33 to shaft 19 to rotate the same,

lit will also be seen that the rotation of the shaft 5 in the direction mention-ed will cause shoulder in to engage and slide rack bar 29 forward, and that said raclr oar through its enga einent with cog wheel 30,

' will rotate the yoke 29 after shaft 19 has been slid forward its full distance through the action of. second or legs 8, and

that this rotation of the yoke efiects 'siniultaneous rotation of said shaft 19 because the beveled gear 33 thereon is turned by travel as a planetgear on the gear 32 which gear 32 in this action acts as a sun gear and is held stationary heeause the cog wheel 25 on shaft is'held from turning oy the spring-retracted rack bar 2%, and. in this connection it willhe noted that-the said raclr her at times etects turning movement or the l9 and at other times causes turning movement of said. shaft 037 preventing turning movement of beveled gear 32.

reference particularly to 3 it will he seen. that when the yoke is turned, shaft 19 is free because the crosspin 18 is free to withdr w from the slot in are lower end oi lever 13 and to guard against any possibility oi backward sliding movement or i9 when disengaged from said slot so-tiiat pin 1% shah reengage said slot when the shaft is hroug it hack to its initial nosition base or tom is provided a curved guide egainsf eh rented by means of a oin 35 which ahuts against the rear side of the yoke; Theguide 3d and stop pin 35 thus insure that the pin 18 shall travel in an are which intersects the slot in lever 18, when said lever occupies its ac vanced position as indicated in Fig. 43, it being noted in this connection that the lever is held in this advanced position by the cam lugs 8 during the swing of the shaft from the tall line position shown in Fig. 3 to the dotted position shown at a same figure. The intermediate dotted position b or the shaft in said figure, represents said shaft when it has been turned a qnarter revolution and the position it represents said shait when it has completed a half revolution. it will he understood in this connection however that the length or swing of the shaft may be Varied by a change in the size of gear wheel 30 and that the extent of the turning noveinent of said shaft during said swing may be varied by a change in the proportion of the sun and planet gear wheels it being oi course apparent that the return rotation of the yoke and oi the shaft 19 is effected by the retractive action of spring 31 and the hack rotation of the planet gear on the sun gear.

Pivoted as to the front end or shaft 19 is the arm or handle 37 of a resilient blade or peel 38, a spring 39 underlying the pivotal point of connection of said shaft and handle and secured to one of said elements at one end and hearing at its opposite end against the other of said elements, this spring yielding to permit downward swinging movement or the peel and reacting to re- -elevate the peel to normal position, and to limit the upward movement of the eel a stop plate so overlies the pivoted end of the peel handle and shaft 19 and is secured to one oi'the same, preferably to the handle of the peel,

ll is an arm rigid with and projecting forwardly from the hose or hottom of th frame-Work adjacent a stop lug 4:2 for posi tively checking the return rotative move ment of the yoke so that the pin e3 project laterally from the peel handle shall normally stand in alineme'nt with and hack of a string-plate a secured upon a lug l-l, girogecting laterally from the arm all, and said spring-plate normally diverges rearwardly upward from the lug, and isprovided with a downwardly and forwardly inclined cancer heel portion are overlapping the rear end of the said lug. Said lug is inclined downwardly and forwardly as indicated in Fig '6, and at its heel or rear lid is beveled downwardly and forwardly to form a earn l5 cooperating with cam a eilecting downward pivotal movement the some is pressed flatly lli naeacee shaft is nearly ended, through the travel of pin 43 upon the underside of lug 44, it being understood that the underside of said lug must slide downwardly and forwardly for the greater part of its length at least in order to holdthe peel pressed flatly on the griddle, during which. movement the peel is adapted to scoop up a cake lying in its path on the griddle, this pickin up of the cake being accomplished just be ore'the forward travel of shaft 19 is completed. During this forward travel of the peel the spring 39 is under tension, and as the forward movement is nearly completed, said spring gradually raises the peel,,due to the fact that the front end of the guide lug 44 is tapered upwardly and forwardly as at 46, this gradual lifting of the peel being necessary as a quick reelevation of the same would tend to flip the cake up from the peel and possibly dislodge it. Just after the spring 39 completes the relevation of the peel as explained and while the same is still held in its advanced position, by the peripheral engagement of cam lugs 7 with nross pin 15, shoulder 11 engages and slides rack bar 26 forward and thereby through the cog wheel 25, shaft 24 and pivoted ears 32 and 33, quickly rotates shaft 19 a ha f revolution, the peel of course turning with the shaft and inverting the cake and dropping it down upon the griddle so that the cake shall be baked upon the other side. Immediately after the cake is dropped back upon the griddle by the peel the shoulder 11 passes out of engagement with the rack bar 26 to permit the spring 28 to return the rack bar to normal position and thus rotate the peel back to its normal positiom and immediately after this action occurs the cam lug 7 passes out of engagement with lever 13 to permit a retractile spring 47 connecting said lever with a fixai arm 48 of the frame-work, to swing said lever back to the position shown in Fig. 1. In the return of the lever and consequently of the slide shaft 19 and the peel, the pin 43 travels back over and depresses the spring-plate 43", so that said plate shall spring up to its original position when the pin 43, clears its rear end,to dispose its cam portion 44 in the path of said pin so that the latter in its next advance movement shall again etlect the depresion of the peel.

The disks are of such proportion and their speed of rotation will be so gaged that by the time lugs 8 come in contact with crosspin 15 of the lever, the baking of the cake will be completed. The engagement of lugs 8 with said pin will cause the peel to advance (sli efiects rotation and travel of the beveled gear 33, and thereby rotates shaft19 for the purpose of turning the peel to discharge the cake into a suitable receptacle, the cake ordinarily dropping off the peel by the time it has attained the position b, Fig. 3. The further swing and turning movement of the peelhowever will insure the discharge of the cake. The peel is swung back to normal position as will be understood from the preceding description of the operation of shaft 19, and at the same time the peel will be rotated back to its initial position so that pin 18 as the backward swing is completed will reenter the slot of lever 13from which it was withdrawn in its initial swinging movement-mud immediately after the pin enteis said slot, the cam 8 passes pin 15 and permits spring 47 to withdraw the peel back to the position shown in full lines Fig. 1.

All subsequent operations are repetitions of those described, it being understood that immediately after a cake is picked up and carried away from the griddle, another charge of batter will be placed thereon to start the baking of the next cake.

From the above description it will be apparent that this machine possesses the features of advantage enumerated as desirable in the statement of the object of the invention, and it is to be understood that it is susceptible of change in form, proportion, detail construction and organization without departing from the principle of construction 7 is concluded, and means for inverting the peel when reelevated.
